To all whom, it may concern.-

Be it known that I, FRANK A. GARLAND, a citizen of the United States,residing at Hoboken, in the county of Hudson and State of New Jersey,have invented certain new and useful Improvements in Wrenches; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and usethe same, reference being had to theaccompanying drawings, and to figures of reference marked thereon, whichform a part of this specification.

This invention is designed to provide a Wrench having a ratchetmechanism which works in the usual manner with a novel feature in theshape of the pawl and the recess in which it slides in the handleportion, the surface of the recess being provided so that when thehandle is operated in one direction to allow the pawl to slide over theratchet the pawl can retreat in the recess, but as soon as pressure isexerted on the handle in the opposite direction to cause the pawl toengage a tooth of the ratchet the pawl is caused to rock in its recessand engage a projection in the recess to cause an operation of thenut-engaging portion of the wrench from the handle.

The invention is illustrated in the accompanying drawings, in whichFigure 1 is a face view of the wrench with a covering-plate removed, andFig. 2 is a similar view showing the wrench when the pawl is engaging atooth to operate the ratchet, and Fig. 3 is a vertical section takencentrally through Fig. 1.

The wrench is provided with a fiat shank 10 to form a handle portion andis provided with a circular head 11, this head 11 being recessed, therecess containing a ratchet 12, provided with the teeth 13 on itsperiphery and having a central perforation 14 to fit a nut or anymachine element to be turned. In the handle portion and continuing as anextension of the recess in the head 11 is a recess 15, that is providedwith a slanting portion 16, which under a certain condition allows arocking of the pawl 17, which is narrow enough to slide down in therecess 15. A spring 18 keeps the pawl in engagement with the teeth ofthe ratchet.

When the handle is operated to the right, looking at the drawings, thepawl will fulcrum at 19 in Fig. 1 and can be easily slid down into therecess 15 against the pressure of the spring 18, and the pawl slidesover the teeth 13 without any hindrance; but when the handle is operatedto the left, looking at the drawings, one of the teeth 13 engages theend of the pawl, the pawl fulcrums at 20, and its lower edge engages aprojection 21 in the wall of the recess adjacent to the slanting portion16. Thus the pawl rocks on the face of the recess that allows thisrocking, and the elements of the wrench are tightly bound together, asshown in Fig. 2.

The parts are easily made and are cheap, and the stability of the wrenchis evident. The portions of the pawl-and-ratchet mechanism are confinedto their places by means of a plate 22, whichis fastened by means of thescrews 23 to the body portion of the wrench. The plate 22 and the head11 are provided with the cut-away portions or perforations 24 and 25,respectively, to allow the engagement by the recess 14 of the ratchet 12with an element to be turned.

This wrench is exceedingly compact and is adapted for all kinds of work,particularly fitting into very narrow places where fiat nuts areemployed and where the operation is difficult.

Having thus described my invention, what I claim is 1. A wrenchcomprising a handle portion having a head on one end, the head having arecess which has an extension extending into the handle portion, theextension of the recess being provided, on one of its walls, with asurface adapted to allow the rocking of a pawl, a pawl arranged to slidein the recess and adapted to rock on the surface, a ratchet havingperipheral teeth and a central perforation, arranged in the recess ofthe head and adapted to be engaged by the pawl, a spring to force thepawl in engagement with the ratchet, and a projection adapted to engagethe free' end of the pawl, when the pawl rocks on the wall of therecess, to cause the pawl to operate the ratchet.

2. In a wrench, a ratchet mechanism comprising a rotatable ratchet-wheelhaving peripheral teeth, a body portion in which the ratchet is mounted,the body portion having a recess adjacent to the ratchet, a pawl in therecess and arranged to slide therein, a spring in the recess to causethe pawl to engage the ratchet, a projection on one wall of the recess,the same Wall of the recess being In testimony that I claim theforegoing I provided With a rocking surface for the pawl,- have hereuntoset my hand this 13th day of whereby when the Wrench is operated in oneOctober, 1906. y direction, the pawl rocks on the rocking sur- FRANK A.GARLAND.
